Catalog and document tools that have adopted llms.txt

It would be cool to have a page on https://llmstxt.org/ that listed existing tools, services, or models(?), that support llms.txt.

There's the [ed](https://llmstxt.org/ed.html) doc which kind of illustrates how you could theoretically use llms.txt with different editors.. but it doesn't have concrete example usage.

I'm imagining tools where if the user enters `https://example.com` as a source of documentation, then the tool automatically looks for `https://example.com/llms.txt` and uses it if it exists...

Start by reading ed.html on llmstxt.org and inspect the existing site pages to find where a tools catalog would fit. Gather concrete tools, services, or models that support llms.txt, with example usage where available; done means the site contains a useful, sourced list rather than only theoretical examples.
